Laser defined as LOT (overall time the pedal depressed) divided Lithotripsy Time (LT; first last including pauses). In vitro studies with TFL lithotripsy suggest decreased retropulsion improved visualization compared laser. These factors may directly impact pauses thus ODC. The objective study was quantify if differences in retropulsion, (100W Empower, Olympus) (Soltive PLS, lasers ureteroscopic procedures. METHODS: A prospective enrolled 62 patients (31 per group) 10–30 mm renal calculi undergoing ureteroscopy fixed dusting settings (0.4J X 60Hz) both 3 endourology faculty. times were collected from logs each case. verified formula (LOT= total energy delivered [J])/(energy [J] x frequency [Hz]) any discrepancy. Retropulsion, visibility, bleeding graded all cases three urologists using 5-point Likert scales. calculated (LOT/LT). Correlation coefficients define relationships stone characteristics. RESULTS: Mean age, BMI, number, density, ellipsoid volume STONE score not significantly different groups (Table 1). more favorably (1.6 vs 2.8), visibility (1.8 3.3) (1.1 1.9) gradings. also had shorter LOTs (380.6 533.6 seconds, p=0.015) superior (49.1% 34.2%, p=0.0001). An inverse correlation found well grading. CONCLUSIONS: findings that be efficient than treatment medium large stones when operated mode. longer especially at higher necessitate future on their thermal implications.
